If your keyboard and mouse not working on macbook, the issue is usually caused by a temporary software glitch, Bluetooth connection failure, corrupted settings, or a hardware detection problem inside macOS. When the keyboard, mouse, or trackpad becomes unresponsive, the MacBook may still be running normally in the background, but it cannot receive input commands. In most cases, you can fix the issue by restarting the system, reconnecting devices, resetting system controllers like SMC or NVRAM, or checking Bluetooth and USB connections.
The situation may feel stressful when your MacBook keyboard, trackpad, or mouse suddenly stops responding. You might not be able to type your password, move the cursor, or even click anything on the screen.
This guide explains why the keyboard and mouse suddenly stop working, how to identify the root cause, and the exact steps you can take to get your MacBook, MacBook Air, or MacBook Pro working again.
What Happens When the Keyboard and Mouse Suddenly Stop Working on MacBook?
When the keyboard and mouse suddenly stop responding on a MacBook, it usually means macOS cannot communicate with the input devices. This may affect the keyboard, mouse, trackpad, or sometimes all three at the same time.
Users often notice symptoms such as:
- The cursor not moving on the screen
- The trackpad stop working when touched
- The keyboard not working while typing
- The MacBook keyboard not responding at the login screen
- The mouse or trackpad refusing to click or scroll
In some cases, the keyboard and trackpad stopped working while the computer is still powered on. You may see the screen active, applications running, or notifications appearing, but your input devices remain unresponsive.
This situation can occur on various models including MacBook Air, MacBook Pro, or even desktop systems like iMac when external devices are used.
The key thing to remember is that the computer itself is often still working fine, and the problem is limited to the input devices.
Why Did My Keyboard and Mouse Stop Working on MacBook?
The keyboard and mouse stop working on MacBook mainly because of software conflicts, Bluetooth connection problems, system controller errors, or hardware communication issues.
Let’s explore the most common reasons in detail.
Software Glitches in macOS
The operating system manages every hardware component connected to the computer. If a temporary software issue occurs, macOS may stop recognizing the keyboard, mouse, or trackpad.
This can happen after:
- A system crash
- An interrupted software update
- Installing new applications
- Changes in system settings
When this occurs, the keyboard and trackpad not working problem may appear suddenly even though the device was working fine earlier.
Bluetooth Connection Problems
If you use a bluetooth keyboard, bluetooth mouse, magic mouse, or magic keyboard, the connection between the device and the Mac may fail temporarily.
Bluetooth problems can occur because of:
- Low battery in the wireless keyboard
- Interference from nearby devices
- Connection conflicts with other Bluetooth accessories
- Corrupted Bluetooth preferences
When this happens, the keyboard or mouse may disconnect and appear completely inactive.
USB or External Device Conflicts
Some people connect an external keyboard and mouse using USB accessories.
If a usb keyboard, usb mouse, or external usb device has connection issues, the Mac may fail to detect the device properly.
Possible causes include:
- A faulty usb port
- Loose cable connections
- Damaged accessories
- Power issues with connected devices
In this situation, plugging the usb keyboard or mouse into another port can sometimes solve the problem.
System Management Controller Errors
The system management controller, commonly called SMC, manages hardware functions such as power distribution, thermal control, and input devices.
If the SMC experiences a glitch, the keyboard, trackpad, and mouse may stop responding.
An SMC reset often restores normal operation.
Startup Configuration Problems
Sometimes the issue appears during startup, especially if system settings stored in NVRAM become corrupted.
NVRAM stores small pieces of data related to system configuration.
If this memory becomes inconsistent, the Mac may fail to detect the built-in keyboard, trackpad, or connected accessories.
Resetting NVRAM can resolve these startup problems.
How Do I Fix Keyboard and Trackpad Not Working on MacBook?
To fix keyboard and trackpad not working, restart the MacBook, check Bluetooth or USB connections, reset the SMC and NVRAM, and update macOS.
Below are the most effective troubleshooting steps.
Restart Your Mac to Restore Keyboard and Mouse
The easiest and often most effective fix is to restart your mac.
A restart clears temporary software conflicts and reloads system drivers responsible for hardware communication.
If the keyboard and mouse suddenly stop responding, try this method first.
Steps to restart the system
- Press the power button once
- Wait for the shutdown options to appear
- Select Restart
If the computer does not respond:
- Press and hold the power button for about 10 seconds
- Wait until the system powers off
- Turn the Mac on again
Many users notice the keyboard working normally again after this simple step.
Check Bluetooth Settings for Wireless Devices
If you use a bluetooth mouse or bluetooth keyboard, connection problems are one of the most common causes of the issue.
How to check Bluetooth connections
- Open System Settings
- Click Bluetooth
- Verify the device is connected
If the device appears disconnected, reconnect it manually.
Sometimes you may need to reset the bluetooth module by turning Bluetooth off and on again.
Also check the battery level of your wireless mouse or magic mouse.
Low battery often causes intermittent connection problems.
Test With an External Keyboard or Mouse
Testing with external mouse and keyboard helps determine whether the issue is related to internal hardware.
Connect a usb keyboard or external mouse to your MacBook.
If the mouse works or the keyboard working normally through USB, the problem may be related to the internal MacBook keyboard or MacBook trackpad.
Using another keyboard temporarily can help you access system settings and perform further troubleshooting.
Boot Your Mac in Safe Mode
Safe Mode helps identify whether third-party software is causing the keyboard or trackpad problem.
Starting the Mac in safe mode loads only essential system components.
How to start Safe Mode
- Shut down the MacBook
- Turn it on again
- Hold the option key during startup
- Choose Safe Mode
If the keyboard and trackpad work normally in Safe Mode, a background application may be interfering with system input devices.
Reset the System Management Controller (SMC)y
Resetting the SMC restores hardware communication and can fix keyboard, trackpad, or power issues.
Steps to reset the SMC
- Shut down the MacBook
- Hold Shift + Control + Option
- Press the power button while holding these keys
- Keep holding for about 10 seconds
- Release all keys and turn on the Mac
This reset refreshes the system management controller, which controls power, thermal sensors, and device communication.
Many MacBook Pro keyboard and trackpad issues are resolved through this step.
Reset NVRAM to Fix Startup Detection Problems
If the problem appears during startup, resetting NVRAM may help.
Steps to reset NVRAM
- Restart the Mac
- Immediately press Option + Command + P + R
- Hold the keys for around 20 seconds
This reset clears system configuration data and restores default settings.
Check for macOS Software Updates
Keeping macOS updated is essential for hardware stability.
Updates often include fixes for:
- Keyboard shortcuts problems
- Bluetooth connection bugs
- Trackpad is not working issues
- Hardware driver errors
To check for updates:
- Click the Apple menu
- Open System Settings
- Select Software Update
Installing updates ensures your Mac runs with the latest fixes.
How Do I Know If My MacBook Keyboard or Mouse Problem Is Software or Hardware?
If the keyboard and mouse not working on macbook starts suddenly after a restart, update, or app installation, it is usually a software issue. If the devices never respond even with external accessories, the problem may be hardware related.
Understanding whether the issue is software or hardware helps you decide the right troubleshooting step without wasting time.
Here are some practical signs you can check.
